GUI fails with DVD and USB stick

[Bejo]

I'm very interested to use this distro but on my desktop pc I can't use the GUI (the console window works).
Linux boots and the AVLinux screen appears with just two icons and the mouse pointer.
I can move the mouse pointer but there is no reaction with the mouse keys. I guess it is a problem of the graphic device driver.
It is a Asus M4A785TD-V EVO board with a ATI Radeon HD 4200 GPU and a AMD Phenom II.

At another PC (laptop) with Intel Centrino everything works fine.
Are there any ideas how to solve this problem?

Thanks in advance

Hi,

This has also been reported elsewhere and seems to be related to Kernel ModeSetting (KMS) and the Xorg RadeonHD driver, so you are correct it's a video driver issue. The answer seems to be adding a 'nomodeset' parameter to the Kernel boot commands. I don't have any ATi or Radeon hardware to test so I'm going to ask you try this new guide here:

Hi,
thanks for the hint but no one of the mentioned options (nomodeset) works.
Additionally I watched at the console window two through running messages:
[drm:radeon_ibschedule]*ERROR*radeon couldn't schedule IB(1...) (counting up till 15? and starts at 1 again)
[drm:radeon_cs_ioctl]*ERROR*Failed to schedule IB

Hi,

If you google this error you will see this is a very widespread problem that affects several distros, It is broken in Xorg which is beyond my control 

Can you try:

Code:

live nomodeset xdrvr=radeonhd

and see what happens?

Hi,

it happens the same

Hmmm,

OK, last thing to try, please tell me if it works or not.

Code:

live radeon.modeset=0

Hi,

great it works 
I was nearly on the way to buy a new graphic card.

Thank you

Phew!

Thanks for getting back to me, this will really be helpful to other ATi users. If you install AV Linux on this machine you will need to make a change to prevent this from happening every time you boot. It requires you change the /etc/modprobe.d/radeon-kms.conf file like this:

Open the Root Terminal from the Accessories menu and enter your Root password, then:

Code:

gedit /etc/modprobe.d/radeon-kms.conf

This will open the configuration file in the gedit text editor, change the existing line 'options radeon modeset=1' to 'options radeon modeset=0' (without the quotes). Then Save the file in gedit.
